I have a project in which i have essentially two main methods. One for testing and one for, well, running the code. Normally you would create submodules, but this is not an option.
file(GLOB sources "*.cpp") file(GLOB headers "*.h") add_executable(testing ${sources} ${headers}) add_executable(main ${sources} ${headers}) So testing should compile all sources except for main.cpp. Main should compile everything but testing.cpp.
The normal way would probably be to create a library from all the sources except main.cpp and testing.cpp, then link this to each executable. However, I guess you mean you can't do that when you say you can't create submodules.
Instead, you can use the list(REMOVE_ITEM ...) command:
file(GLOB sources "*.cpp") file(GLOB headers "*.h") set(testing_sources ${sources}) list(REMOVE_ITEM testing_sources ${CMAKE_CURRENT_SOURCE_DIR}/main.cpp) list(REMOVE_ITEM sources ${CMAKE_CURRENT_SOURCE_DIR}/testing.cpp) add_executable(main ${sources} ${headers}) add_executable(testing ${testing_sources} ${headers}) 
list sub-command REMOVE_ITEM requires list to be present. error under cmake 3.5.0, windows 10 with the code above.
list(REMOVE_ITEM ${sources} ...) rather than list(REMOVE_ITEM sources ...)), or your list is empty.
${CMAKE_CURRENT_SOURCE_DIR} in front of the filename to be removed, but it doesn't work. Prepending the filename(s) with ${CMAKE_CURRENT_SOURCE_DIR} is mandatory. My 2 cents. Ste
